Step-by-step explanation: Just copy the other cone and find half of the diameter to find the radius the cones are congruent.
They each contributed $6.75. I got that because i divided the $27.00 by the 4 friends and got $6.75, to make sure I also multiplied the $6.75 by 4 and got $27.00
1. opposite sides are equivalent , opposite angles are equivalent
2. 4 sides, 4 angles, both answers for number one also work
3. A square
To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
